' runsnn-nonnnn ATTACHMENT Application filed J'anuary 18, 1939., Serial No.'421,806.

The object of my invention is to providea simple, practical and inexpensive contrivance to be attached to an ordmary Bunsen burner for performing operations'needful tion comprises a funnel-shaped gas cham-' her, the nipple of which is set onto the nozzle of a Bunsen burner, and the top of which is closed and sealed by a cap member which is provided with orifices around its inner wall to produce a series of radially, inwardly horizontal flames guided by deflector lugs 2 onto a platform centrally positioned, whereon is placed the dental investment or article to be heated The wax, if there be any as a component of the article heated, when molten by the heat of the flames, flows off said platform in sluices therein provided into a trough in said cap member, and is drained ofl through a pipe connected with said trough.

In the accompanying drawings, forming a part of this application, similar characters of reference indicate corres ondin arts in p g p '4. In an attachment ofthe character dea all the views. i

Figure 1, show-s my invention attached to a Bunsen burner.

Figure 2, is a top viewof my present invention. 1 y

Figure 3, is a vertical;cross-section of my invention, at line 3-3 inFigure 2.

Referring to the drawings, 4 is a'sheets metal or cast, circular funnel-shaped gas chamber, the nipple 5 of which sets onto nozzle 6 of a Bunsen burner 7, and the top of which is closed and sealed by cap member 8. Cap member 8 is shaped so as to form and include a vertical wall 9, a trough 10,

and a horizontal platform '11. Wall 9 is provided with a series of equidistant, radialdischarging orifices 12, each'of which ori- 1 oes is provided with a deflector'lug 13.

Platform 11 is provided with a series of sluices 14. To trough 10 is connected a drain pipe 15, i
